Libya's daily oil production has been restricted to 100,000 barrels from floating oil rigs; 90,000 barrels pumped via pipeline to the Al-Hariqa seaport; and 400,000 barrels pumped tothe Al-Brega seaport, the official, who holds a senior position at state-owned energy firm OiLibya, told The Anadolu Agency.
Libya's oil production has been significantly affected since the country's two largest oil export terminals – Sidra and Ras Lanuf – were forced to close less than two weeks ago amid clashes between rival militias.
Prior to the terminal closures, Libya had been producing 550,000 barrels a day, which was already down from 800,000 barrels per day at the beginning of December.
"There are strict instructions not to disclose current oil output to the media," the official, requesting anonymity, said.
Those instructions, he added, had been imposed by Omar al-Hassi, who was appointed prime minister by Libya's outgoing General National Congress.
Fierce clashes erupted earlier this month between members of the "Dawn of Libya" Islamist militia and security personnel guarding petroleum facilities in eastern Libya.
Libya has remained dogged by instability since the 2011 ouster and death of longstanding ruler Muammar Gaddafi. Prior to Gaddafi's ouster, Libya's daily oil output had stood at 1.5 million barrels.
In the three years since, rival militias have often locked horns, frequently bringing violence to Libya's main cities, including capital Tripoli and eastern Benghazi.
The sharp divisions have yielded two rival seats of government in the country, each of which has its own institutions.
Two assemblies currently vie for legislative authority: the House of Representatives, which convenes in Tobruk, and the General National Congress, which – even though its mandate ended in August – continues to convene in capital Tripoli.
The two parliaments support two different governments respectively headquartered in the two cities.
